Table_2_Diverged and Active Partitiviruses in Lichen.XLSX

The lichen is a microbial consortium that mainly consists of fungi and either algae (Viridiplantae) or cyanobacteria. This structure also contains other bacteria, fungi, and viruses. However, RNA virus diversity associated with lichens is still unknown. Here, we analyzed RNA virus diversity in a lichen dominated by fungi and algae using dsRNA-seq technology and revealed that partitiviruses were dominant and active in the microbial consortium. The Partitiviridae sequences found in this study were classified into two genera, which have both plant- and fungi-infecting partitiviruses. This observation suggests that the lichen provides an opportunity for horizontal transfer of these partitiviruses among microbes that form the lichen consortium.

地衣是一类主要由真菌与藻类（绿色植物亚界Viridiplantae）或蓝细菌构成的微生物共生联合体。该共生结构中还包含其他细菌、真菌与病毒。然而，目前与地衣相关的RNA病毒多样性仍未明确。本研究采用双链RNA测序（dsRNA-seq）技术，对一类以真菌和藻类为主导的地衣中的RNA病毒多样性进行了分析，结果显示多分病毒（partitiviruses）在该微生物共生体中占据优势且具有活性。本研究中获得的多分病毒科（Partitiviridae）序列可被划分为两个属，这两个属的病毒均包含侵染植物与真菌的毒株。该观测结果表明，地衣为构成其共生联合体的各类微生物之间提供了这些多分病毒发生水平转移的契机。
